Sodium Hydroxide → 3-{4-[1-(4'-tert-Butyl-biphenyl-4-yloxy)-3-methyl-butyl]-benzoylamino}-2(R)-hydroxy-propionic acid

Participants

Reaction Steps

To a mixture of 3-{4-[1-(4′-tert-butyl-biphenyl-4-yloxy)-3-methyl-butyl]-benzoylamino}-2(R)-hydroxy-propionic acid methyl ester (60 mg, 0.12 mmol) in methanol (2 mL) is added sodium hydroxide (5 N aqueous, 0.5 mL) and stirred for 5 h. The reaction mixture is concentrated and acidified by 5 N HCl (0.5 mL), extracted with ethyl acetate. Combined organic layers are washed with water and brine, dried over sodium sulfate. Concentration gives the title compound (63 mg). MS (ES): 504.3 [M+H]+.
